Product description

Product description Our Marine Ammonia Checker HC (HI784) is designed to accurately and quickly determine the ammonia level in marine (saltwater) samples. The digital readout makes measurements effortless. Range: 0.00 to 2.50 ppm (mg/L) NH3 Built-in timer so you don't miss a step Saltwater Compatible Our Ammonia Checker HC (HI784) provides an uncomplicated, highly accurate, and budget-friendly way to measure ammonia (NH3/NH4+) in saltwater/marine environments. Ammonia is naturally found as part of the nitrogen cycle of a tank as aquarium organisms produce it as waste. In a balanced tank, the majority of ammonia is consumed by bacteria and the nitrogen cycle continues. When out of balance, ammonia toxicity can wreak havoc on tank inhabitants. It is important to monitor ammonia levels to ensure they remain steady and low. The ammonia checker is designed as an exceptionally accurate alternative to chemical test kits, our Marine Ammonia Checker (HI784) provides quick, accurate results in a few easy steps. Ammonia Checker Tips & Tricks for Accurate Measurements Ensure the sample does not contain any debris. Hold dropper bottles completely vertically and squeeze slowly to ensure correct drop size. Whenever the cuvette is placed into the checker, it must be dry outside and free of fingerprints, oil and dirt. Wipe the cuvette thoroughly with HI731318 microfiber cleaning cloth or a lint-free cloth prior to insertion. Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette. Do not let the reacted sample stand too long after reagent has been added, as accuracy will be affected. Discard the sample immediately after the reading has been taken or the glass might become permanently stained. Prepare sample cuvette immediately after collecting sample from tank. Ammonia is volatile and will dissipate if stored in a bottle before analysis, causing low measurements. Directions 1. Ensure the sample does not contain any debris. 2. Hold dropper bottles completely vertically and squeeze slowly to ensure correct drop size. 3.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
